IMPROVEMENT IN METAL-ROLLING MACHINERY.

Specification forming part of Letters Patent No. 175,904, dated April11, 1876; application filed February 11, 1876.

To all whom it may concern:

Be it known that 1, JOHN BEAVIS, of Cleveland, in the county of Ouyahogaand State of Ohio, have invented certain new and useful Improvements inMachinery for Rollin g Metal, &e.; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it pertains to make anduse it, reference being had to the accompanying drawings, which formpart of this specification.

My invention relates to an improvement in machinery for making wire orbars of metal by the process of rolling.

In the drawings, Figure 1 shows, in front elevation a train of rolls,part two-high and part three-high, with my invention attached. Fig. 2 isa view taken in cross-section. Fig. 3 is a detached view, showing themanner in which my viaducts open to permit the escape of the bar or wirewhen necessary.

My invention consists,first,in channelguides or viaducts, in combinationwith one or more sets of rolls, said viaduets being constructed toautomatically expand and allow of the escape of surplus metal as itaccumulates therein second, in said channel-guides or viaducts adaptedtoopen or unfold in such a way as that, after they shall have performedthe offiee of receiving from one pass and delivering into another, thesurplus or slack of the bar or wire may be permitted to escape.

A A represent rolls, of any style or description. B is a viaduct toreceive from the lower passes of three-high rolls and deliver to theupper passes of the same, or vice versa. 0 is a viaduct to receive fromthe upper passes of a set of three-high rolls and deliver to the lowerpasses of a neighboring set of a train, or vice versa. D is a viaduct toreceive from the upperpasses of a set of three-high rolls and deliver toa neighboring set of twohigh rolls in a train, or vice versa. Eachviaduct is made in two longitudinal parts, hinged or jointed together insuch a manner that their component parts can open or unfold, and permitthe escape of the contents.

Operation: The rolls A may be of any nature or description, inasmuch asthey form no part of my invention, and as my invention is equallyapplicable to rolls of any description. The viaducts A, B, G, or D aresupported in any suitable manner, so that they shall be held stationaryin the proper position. To this end they may be fixed upon posts orstandards E, or they may be held by brackets from the frame of therolls, or in anyother desired manner.

To illustrate the operation of my invention, it is only necessary todescribe the working of a single viaduct, and for that purpose we willselect the one marked B in the drawings. We will suppose that it is toreceive from the upper tier of passes and feed or deliver at the lowertier. The rod or wire as it is fed in at the upper pass is directed andpropelled directly into the viaduct B, and is thereby directed downward,and properly fed into the i proper pass below.

As the operation of the upper and nether rolls progresses, there will bemore or less surplus or slack in the material being rolled, and if theviaduct was a solid piece it would soon become gorged and inoperative.

To obviate this difiiculty I have provided a means of opening theviaduct automatically, by constructing it of the two longitudinalsections shown, and hinging them together in such a way that this slackor overplus just mentioned shall of itself serve to open the viaduct andpermit an escape of said overplus.

The only function of my viaducts is to afford a primary guide ordirector of the bar or wire from one pass to another of a set or trainof rolls. In other words, my viaducts are intended merely to receivefrom one pass and to guide and feed into another pass upon the rolls.This done, their function is accomplished; and to prevent theirafterward being of detriment, I have constructed them to permit theescape of their contents, as may be necessary.

I do not limit myself to any particular shape or fashion of my viaducts,as they must needs be varied in this particular to meet special requirements.

What I claim is- 1. The combination, with rolls for rolling metal orother substances, of the guide or viaduct herein described, said viaductbeing constructed in two longitudinal sections, and

adapted to open or unfold, substantially as, and for the purpose setforth.

metal or other substances, of one or more guides or viaducts,constructed substantially as herein described, and placed so as toproperly receive and deliver and at the same time constructed to open orunfold, substantially as and for the purpose set forth.
